Effect of stress-relief anneal time on residual stress of Co-Cr-Mo parts manufactured with selective laser melting [PDF]

open access: yesMATEC Web of Conferences, 2022
Thermal inconsistencies inherent in the selective laser melting manufacturing process generate residual stress that may exceed the yield strength of the material resulting in deformation and cracking of components. This may however be mitigated through a

Theoretical stiffness limits of 4D printed self-folding metamaterials

open access: yesCommunications Materials, 2022
The 3D stiffness of a self-folded metamaterial structure is limited by the low stiffness required by the folding process. Here, the stiffness limits of self-folding bilayers are theoretically established by a nonlinear model and experimentally validated ...
